SPECIFICATION forming part of Letters Patent 350."???5361, dated November 1, 1904.. Application filed April 18, 1904. Serial No. 203.581. lilo model.)

To all whom it may concern:

Be it known that I, C ARLES E. MORGAN. a citizen of the United States, residing at Cleveland, in the county of Cuyahoga andfitate of Ohio, have invented certain new and useful Improvements in Storage Batteries; and I do declare that the following'is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to storage batteries; and the object of the invention is to provide abattery which is especially adapted for portable uses, as in automobiles and the like corn structed to be driven by electric power and necessarily carrying the source of power with them.

Hithertothe electrically driven or propelled vehicle has been largely objected to on ,accountof the excessive load it has to carry to get the requisite amount and continuity of power for anything like a prolonged journey, such as a run of four to six hours, and which has necessitated the construction of a correspondingly heavy-vehicle which could carry the load and not soon be racked to pieces. In all this the objection lies against the excessive weight of the battery itself, which is out of all proportion to the power stored and available, and hence I have conceived the idea of a battery in which the storage capacity will at least not be diminished, if it be not really materiallyincreased, but which has the exceptional merit of lightness in pounds avoirdupois as compared with the batteries in common use.

To these ends my invention consists in a storage-battery plate constructed and adapted to operate substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective inside view of one side or section of my new and improved plate, and Fig.

2 is a vertical cross-section of a complete plate filled with the active material. Fig. 8 is an enlarged cross-sectional view ofa-portion of onset the sides or: sections of the complete plate and disclosing the electroplating or 'deposit upon its surface. I Y I As thus shown, A represents the entire plate as seen in vertical section, Fig. 2, and

a and a, respectively, represent the sides or sections constituting the said plate. Structurally the said sides or sections are alike and each is provided on its inside with a series of pockets formed by vertical ribs 'or walls 2 and cross-walls 3 atintervals, and. the said walls match in the two sections and form pockets or chambers equal to the depth'oif both sets of ribs brought together. These pocketsmay have'greater or less depth, as

shall be found. preferable, and the-two sides are bolted, riveted, or brazed together, as preferred, and have a common binding-post 4 at their top.

Heretofore in storage batteries familiar to me the plate or element has been made of lead or a lead alloyand has served as a' support for the active material, whether, applied to the plate as a paste or developed upon orfro'rn the plate by electrolytic action; but the body of lead thus put into the plate made it unduly heavy, and hence objectionable, asal'read y described. I overcome and avoid this objection by using an aluminium body or support cast into a grid or equivalent form, and then I electroplate the same with nickel or other relatively cheap conducting metal, which will help to protect the plate from the action'oi' the electrolyte 6. Then having provided a light-weight and good conducting support which is exceptionally rigid and strong and ously and finely perforated to promote circu- J ales and said particles and plate electroplated lation-and electrolytieaetion, and any suitable r with aconductingmetal, and active material eleettelyte may be used. filling the interstices of said particles, sub:
